Double Glazing Repairs
Repairs are possible when double-glazed windows become difficult to open or exhibit signs of condensation. In many cases, this can be done without the need to replace the entire window unit.
It is best to delegate the installation of double glazing to professionals.
Condensation
Condensation in your double-glazed windows isn't just annoying it could also mean that warm air is escaping your home. This is usually the indication of a damaged seal or deterioration. It is recommended to replace the entire window if this is the case.
In some instances, you may be capable of using a hairdryer (from a safe distance) to remove the moisture between the glass panes. This is a temporary solution but you should seek help from a professional whenever you can. The longer the problem persists, the greater the damage to your double glazing and even to your health.
If the condensation is limited to a tiny portion of your window frame it is usually possible to get rid of it by wiping it away frequently and swiftly. However, if you see condensation in larger areas of your window, this could indicate that the seal has been damaged and the windows are now less efficient thermally than they need to be.
Internal condensation can be caused by a variety of reasons however, it's usually due to excessive humidity and/or poor ventilation around the house. Humidity can easily create droplets of water on cold surfaces, which is why your double-glazed windows are more likely to exhibit condensation than older single-pane windows. Install an air vent in your kitchen or bathroom when it is extremely humid.
If your windows remain within their warranty you can contact the company who installed them to explain the problem and ask them to rectify it for you - they might be able to replace the unit, or they may have to install one-way air vents in order to stop any further condensation. This is a better option than replacing your double-glazed windows as you will save money and time.
Foggy Glass
Foggy windows indicate that the seal on double-paned windows has failed. They have two glass panes that have space between them and this space is filled with energy-efficient gases such as argon or krypton. This helps keep temperature-controlled air inside your home, while keeping the outside elements out. However, if the seal fails, water could get in and cause fog. Foggy windows can make your home less efficient and unattractive.
While you can replace your windows if they are fogging, many homeowners prefer to hire a professional for window repair instead. Before making a recommendation, a glass specialist can help determine if the windows are repairable. If they need to be replaced, they will be able to supply you with a premium replacement that won't be prone to foggy glass.
Another common problem with double glazing that is encountered is that the doors or windows becoming difficult to open or close. This could be due to extreme weather conditions or a change to the frame's structure. If double glazing repairers find that your double-glazed is difficult to open, the first step is to speak to the business you purchased it from. The majority of companies offer guarantees on their products that last for a an agreed period of time. Some even offer lifetime guarantees.
If you're unable to solve the issue with your provider It could be time to switch. Always request a written confirmation of your complaint, along with any agreements made and the dates. If you are required to change providers, this will be easier.
The windows that are stained with a haze can be fixed through defogging, a process that involves drilling holes into the window, injecting cleaning solution and then removing the soiled liquid, and drying the inside of the glass. This is a relatively new solution and is worth a second look to determine whether it's right for your home prior to committing to it. Remember, however that it can't replace any energy efficiency loss from deteriorated window seals.
Cracked Panes
A crack in a double-glazed window may seem like a minor problem however it could cause significant damage. It's crucial to have the crack fixed as quickly as you can to avoid further damage especially if it's on the inside of the glass.
Double-paned windows are made up of two panes of glass which are joined together. The space between the panes is filled with inert gasses, such as argon and krypton. This is done to stop heat from your home from moving through the glass. The gas also slows the transfer of heat, so that the warm air in your home can move more slowly through the window than when there was nothing between the two glass panes.
It's crucial that the windows are installed correctly and with a good seal. A licensed glazier should be able to install the windows as they can seal them tightly to ensure the best insulation. If the seal on the window has failed and gas is trapped inside the panes could leak out and reduce their insulation properties, which could lead to cracks between the panes.
Another reason that causes broken double-pane windows can be due to inadequate installation, which could cause the glass to expand and contracting at different rates. This can lead to stress cracks that appear over time and can weaken the glass. If this happens, you should find a glazier that can replace the damaged glass with one that is better suited to your home.
If you discover a tiny crack in your double-glazed windows, it is important to know that the crack is not repaired by filling it with adhesive. Double-paned windows depend on an elongated seal between the two panes and any cracks will only worsen as time passes.
It is important to remember that broken glass can be dangerous. Therefore, it's recommended to consult a professional who has the proper tools to do the job. They will also know how to get rid of the old sealant without causing damage to the glass.
Seals that leak
The IGU consists of three or more sheets of glass that are annealed or glass that has been tempered. The IGU is fixed by a combination of aluminum spacers, polyurethane. This creates an airtight seal that prevents moisture from entering your home. In time, however, the seal can break down which allows water and draughts to get into your living spaces.
This is usually due to the natural expansion or contraction of materials used to make your window. The sealant (silicone or polyurethane) can shrink and stretch slightly in response to changes in temperature and humidity and can put IGUs at risk of failure. If the seal is damaged the fill-gas that is insulating could leak and leave your windows with an appearance of fog and draughts that decrease the efficiency of your home.
If the window seal fails, it can cause condensation or water to form between the panes that you are unable to wipe away. In certain cases the condensation may cause an indestructible stain on the glass of your window.
Generally, you can fix the issue by having your windows professionally defogged and resealed. This process requires specialized equipment that removes water, fills the gap with the gas argon or krypton and then reseals the window without letting gas escape. The cost can differ based on your location and the type of IGU, however, most double-glazed windows can be repaired in an hour or less.
In addition to replacing your window seals there are other ways to improve the efficiency of your double-pane windows. Choose energy-efficient coatings and glazing that reflect rather than absorb the sun's rayons. This will keep your living spaces cooler and more comfortable as well as enhance the appearance of your windows. Lastly, use caulk or weatherstripping around your frame of your window to eliminate gaps that may let cold air into your home and warm air to escape. In some instances it is a better alternative to replacing the entire window.
